Upper manifold on V6
 
I am about to replace my noisy manifold with a spare quiet one. Should I dismantle and clean out the spare before fitting?

The problem with dismantling is you basically have to chisel the lid off of it with potential for damage (I have done it and it's a chore) and then glue it back on.
You may be best to just dump a couple of litres of degreaser in it, slosh it around and leave it to evaporate for a few days. (It may be easier if you have an air compressor to blow it out)
On the other hand it will be oiled up after a couple of days anyway so probably futile!:shrug:

No, no and thrice no!

These things were constructed in Satan's own workshop using dark forces beyond the comprehension of mortals.

Be happy when they work. Shrug stoically when they don't.

Thanks for the very useful comments. Will leave well alone.

I should have mentioned that the manifold that I opened up and sealed back up doesn't work worth a darn. I'm not sure if it was my fault or not but there is too much drag on the valve operating rod. One day I may open it up again and see what's going on but as Lord of Hog says they really are the spawn of the devil so I will continue shrugging stoically as long as my current one works.

Replacing the inlet manifold
 
I know this is a well discussed topic. I assume that the only sensible way to go is to buy a new one or take the guts out of the existing one. Is there any other option? I just grin and bear in my 2004 KV6 with 100,000kms.

No other option other than the ones you have mentioned I'm afraid, there was someone on FB developing alloy inlets but I'm not sure how far that got?

I wonder what Kia used on the Magentis? :shrug:

No VIS ?

Catch tank
 
What are the thoughts on fitting an oil catch tank to prevent oil getting into the manifold? Any recommendations would be appreciated.

Rich in Vancouver 8th November 2019 03:18

I fit an oil catch tank on my V6 Freelander. It certainly collected fluid but the manifold still got oily. I found if I forget to empty the tank every couple of weeks, and it overfilled the car would run terribly.
More than once I thought it had a major issue when it was just choking on the slop in the can.
Eventually I just removed the catch tank and fitted a pair of sealed VIS motors.
